Description
FSC230/10 10A Fan Speed Controller (230V AC)
The FSC230/10 Fan Speed Controller is a high-performance single-phase phase-angle power regulator designed for precise control of inductive loads such as fans, motors, and pumps. Engineered for industrial and commercial applications, this DIN rail-mounted controller delivers smooth and adjustable voltage output, ensuring optimal performance and energy efficiency.
Designed to operate on 230V AC supplies, the FSC230/10 supports loads up to 10A (2.4kW), making it ideal for HVAC systems and general motor control applications. Its advanced phase-angle control allows for fine-tuned speed regulation, while the integrated soft-start and minimum speed adjustment ensure reliable motor operation without stalling or sluggish performance.
The unit includes built-in protection features such as an RC snubber network for inductive loads, an integral RFI filter for reduced electrical noise, and high surge current capability via a robust TRIAC. With compatibility for multiple control signal inputs (0–5V, 0–10V, and 4–20mA) as well as manual potentiometer control, the FSC230/10 offers exceptional flexibility for system integration.
Compact, reliable, and easy to install, the FSC230/10 is an ideal solution for engineers and system integrators requiring precise and dependable motor speed control.
